Campanula plant named ‘Viking’

ABSTRACT

A new and distinct cultivar of  Campanula  plant named ‘Viking’, characterized by its upright plant habit; freely basal branching habit; freely flowering habit; and violet-colored campanulate-shaped flowers.

Botanical designation: Campanula hybrida.

Cultivar denomination: ‘VIKING’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Campanula plant, botanically known as Campanula hybrida and hereinafter referred to by the name ‘Viking’.

The new Campanula plant originated from a cross-pollination in IJsselstein, The Netherlands in May, 2004, of a proprietary selection of Campanula hybrida identified as code number Ca 402-01, not patented, as the female, or seed, parent with a proprietary selection of Campanula hybrida identified as code number Ca 406-01, not patented, as the male, or pollen, parent. The new Campanula was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Zuidwolde, The Netherlands in June, 2007.

Asexual reproduction of the new Campanula plant by tissue culture in The Netherlands, since October, 2007, has shown that the unique features of this new Campanula plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Campanula have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Viking’. These characteristics in combination distinguish ‘Viking’ as a new and distinct cultivar:

-   -   1. Upright plant habit.     -   2. Freely basal branching habit.     -   3. Freely flowering habit.     -   4. Violet-colored campanulate-shaped flowers.

Plants of the new Campanula differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Campanula have longer flowering stems than         plants of the female parent selection.     -   2. Plants of the new Campanula have larger leaves than plants of         the female parent selection.     -   3. Plants of the new Campanula flower for a longer period of         time than plants of the female parent selection.

Plants of the new Campanula differ from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Campanula have lighter green-colored leaves         than plants of the male parent selection.     -   2. Plants of the new Campanula are more freely flowering than         plants of the male parent selection.     -   3 . Plants of the new Campanula have larger flowers than plants         of the male parent selection.

Plants of the new Campanula can be compared to plants of Campanula ‘Sarastro’, not patented. In side-by-side comparisons, plants of the new Campanula differed from plants of ‘Sarastro’ in the following characteristics:

-   -   1. Plants of the new Campanula were more compact than plants of         ‘Sarastro’.     -   2. Plants of the new Campanula were more freely flowering than         plants of ‘Sarastro’.     -   3. Plants of the new Campanula had violet-colored flowers         whereas plants of ‘Sarastro’ had dark purple-colored flowers.

The photograph at the top of the second sheet is a close-up view of typical flowers of ‘Viking’.

The photograph at the bottom of the second sheet is a close-up view of the upper surface of a typical leaf of ‘Viking’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following description were grown under conditions which closely approximate commercial production conditions during the summer in an outdoor nursery in Zuidwolde, The Netherlands. During the production of the plants, day temperatures ranged from 14° C. to 32° C. and night temperatures ranged from 6° C. to 18° C. Plants had been growing for six months when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
